DUNLEAVY, or PLYMOUTH, PENNSYLVANIA Y FLYER FOR SPINNING Application filed March 24,

This invention relates to improvements in fiyers for thread spinning and thread twisting machines, and has for one ofit-s ob ects to provide an improved flyer of s1inple, practical' and economical construction by means of which there is secured such a uniform tension on the thread as will reduce to a minimum the breakage incident to spinning and twisting operations, thereby obtaining 1ncreased efficiency and production.

Another object is to mount a flyer arm in such manner that the same will be securely maintained in position on the flyer body and at the same time be easily and quickly're-' moved therefrom for replacement purposes.

A further object is to so mount the flyer arm or arms upon. the body that the same will be securely retained thereon in a position where accidental contact of the hands of an operator with the retaining means, while the flyer is in operation, will be avoided.

The above and other objects will'appear more clearly from the following detailed description, when taken in connection with the accompanying drawing, which illustrates a preferred embodiment of the inventive idea. V y

In the drawing Figure 1 is an elevational view showing the improved flyer mounted upon a spindle in association with a bobbin thereon;

Figure 2 is a fragmentary vertical sectional view taken substantially on the line 2-2 of Figure 1; a

Figure 5 is a plan view of one of the arms or Wires;

Figure 6 is a perspective view of the flyer showing two arms or wires carried thereby; and Y Figure 7 is a bottom plan view of the construction shown in Figure 6.

Referring more particularly to the accompanying drawing, the, numeral 10 indicates a spindle of a spinning or like machine having the usual tapered extension 11 upon AND LIKE MACHINES 1928. Serial No. 264,387.

which is mounted the bobbin 12 containing the thread or threads to be twisted, the spindle 10 being rapidly rotated in the customary manner as by the engagement of a belt with the main portion of'the spindle.

The flyer, which includes the essential features of the present invention, comprises a body preferably made of wood andconsisti'ng of ahub portion 13 with a disk-like portion 14 at one end of said hub portion and extending laterally therefrom. The body is provided withja central opening for receiving the ex tension 11 of the spindle after the bobbin 12 has been mounted thereon and saidopening is suiiiciently large to permit of a free rotation of the flyer about the spindle' when in operation, The end of the hub portion 13 opposite the disk 14 is adapted to rest against theadjacentend of the bobbin 12 with the undersurface of thedisk 14 opposed to said end of the bobbin and in spaced relation thereto.

To reinforce the-disk 14 and provide a means for supporting the flyer arm or arms on the body of the flyer, there is preferably I,

provided a metal cap 15 having a central opening forreceiving the hub portion 13 and engaging the under surface of said disk with the outer edge of the cap turned upwardly about the periphery of the disk 14 and terminating substantially flush with the upper surface of said disk.

, The retaining means for supporting the flyer armor arms upon the body of the fiver is preferably formed upon the under surface of the cap 15 so as to minimize the possibility of an operators hands coming in contact with said means while the flyer is'in operation. The retaining means comprises two pairs of. lugs 16 struck from the cap 15 on diametrically opposite sides of the hub portion 13 with said lugs extending in opposite directio'nstoward each other and the free ends thereof spaced to form an entrance open ing 17 therebetween for the flyer arms. Also at oppositely disposed points the cap 15 is providedv intermediate the pairs of lugs 16 with othersingle lugs 18 each of which extends in an opposite direction from the adjacent lugs of the pairs 16. With this (mm struction one or more flyer arms or wires 19 and 20 may be secured in position on the underside of the cap 15 by engagement with a series of lugs, with the free ends of the wires extending on opposite sides of the flyer body. The wires19 and 20 differ-in construction only in that the former has its extremities 21 bent so that when the wire is in position said extremities will extend downwardly, as shown in-Figure 1, while the extremities of the wire 20 are in the sameplane as the remaining portion of thewire. When two such wires are used, as shown in Figure '6, the

loops of the respective wires, throughwhich thethreads are passed, will be in different horizontal planes and will havethe effect of exerting a strong tension or pull upon the threads passing through said loops at an angle to the wires.

Each of the arms or wires is bent intermediate its ends to provide angular portions 22 which diverge from' a common point 23. WVhen mounting a wire upon the body of the 'flyer the pointf23 is first engaged beneath one of the lugs 18 and then by a spring action the ends of the angular portions may be inserted through the opposed openings 17 be tween the lugs of each pair 16. Then, due to the resiliency of the wire, the portions thereof contiguous to the ends of the angular portions 22 will engage beneath the lugs 16 adjacent the lug 18 with which said wire is h eld Thus the wire or arm is securely ati tached to the flyer body and may be readily detached therefrom by a reversal of the operationvjust described when it is desired to rewire the flyer. v I

In cases where two wires are employed as in Figures 6 and 7, the second wire is mounted in'the same manner as above described, and said wires are then bent, as clearly shown in Figure 7, to diverge outwardly from the pairs oflugs 18 to separate laterally the loops at the extremities of the wires. i After mounting a flyer upon the extension 11 of the spindle above the bobbin 12, as shown in Figure 1, the milled nut or head 24 having a tapered opening therethrough is forced upon the upper extremity of the extension 11 so as to be tightly wedged thereon, said head forming an abutment which will prevent accidental detachment of the flyer from the spindle while in operation.

What is claimed is:

I 1. A flyer comprising a body adapted for rotation on a bobbin spindle and having an under surface, a cap secured to said under surface and having flyer arm-retaining lugs contiguous to said surface, and a flyer arm supported by said lugs.
